- FIG. 7 is a schematic diagram of a user plane protocol stack between a second terminal device, a first terminal device, and a base station (eNB).
- Architectures of a control plane protocol stack and a user plane protocol stack used between the second terminal device and the eNB can enable the eNB to directly manage the second terminal device, so that the eNB can configure parameters of a control pane and a data plane of an RRC connection for the second terminal device, for example, configure security parameters of data and signaling transmitted from the second terminal device to the eNB.
- a peer-to-peer RRC layer and a Packet Data Convergence Protocol (Packet Data Convergence Protocol, PDCP) layer between the second terminal device and the eNB.
- the RRC layer is responsible for managing parameter configuration of an access link of the second terminal device and establishing a bearer of the second terminal device.
- the bearer of the second terminal device includes a radio bearer for accessing the eNB by the second terminal device and a bearer from the eNB to a core network.
- the second terminal device On a user plane, for uplink data, the second terminal device processes an Internet Protocol (Internet Protocol, IP) data packet of an upper layer on a PDCP layer, and then the first terminal device forwards the processed data packet to the eNB.
- IP Internet Protocol
- the eNB For downlink data, the eNB sends a data packet of the core network to the PDCP layer for processing, and then the first terminal device forwards the processed data packet to the second terminal device.
- the control plane protocol stack and the user plane protocol stack are used.
- a core network device such as a mobility management entity (Mobility Management Entity, MME), a serving gateway (Serving Gateway, SGW), or a packet data gateway (Packet Gateway, PGW)
- MME mobility management entity
- SGW serving gateway
- PGW packet data gateway
- the second terminal device is directly connected to the eNB by using a UU interface, so that compatibility of the core network can be maintained.
- the eNB can still store a context of the second terminal device, so that a transmission capability of service data can be rapidly restored, a mobility processing procedure is simplified, and a delay is reduced.
- an RRC context of the second terminal device is directly managed by the eNB, and only the second terminal device and a PDCP layer of the eNB participate in integrity protection, encryption, and decryption of signaling and data transmission, and therefore relay UE cannot decrypt signaling and data of the second terminal device. This ensures security of communicating by the second terminal device with the eNB by using any first terminal device.
- the following embodiments provided in the present invention provide a solution to a transmission problem of a security parameter required for secure communication between a second terminal device and a cellular network.
- Step 801 A second terminal device sends radio resource connection management signaling to a first terminal device, where the first terminal device has a relay function.
- the radio resource connection management signaling is used to request to obtain a security parameter.
- the radio resource connection management information belongs to RRC signaling.
- the radio resource connection management signaling carries an identifier of the second terminal device.
- the second terminal device sends the radio resource connection management signaling to the first terminal device, and the first terminal device needs to determine that the radio resource connection management information is to be forwarded to a network side device.
- the second terminal device sends the radio resource connection management signaling to the first terminal device by using a dedicated air interface resource.
- the dedicated air interface resource is used to forward signaling of the second terminal device to the network side device.
- the dedicated air interface resource may be a dedicated physical resource or a dedicated logical channel entity.
- D2D communication is used as an example.
- An added feature of LTE-D2D may enable a data packet to be sent between the second terminal device and the first terminal device by using the dedicated air interface resource.
- a dedicated bearer D2D-data radio bearer (Data Radio Bearer, DRB) is established between the second terminal device and the first terminal device, and the D2D-DRB is assigned to be specially used by the first terminal device to forward signaling or data of the second terminal device to the network side. That is, the first terminal device forwards, to a base station, the signaling or the data of the second terminal device received by using the D2D-DRB.
- DRB Data Radio Bearer
- the first terminal device does not need to parse a received data packet, and only needs to determine whether to receive the data packet by using the dedicated air interface resource, so as to determine whether the data packet needs to be forwarded to the network side device.
- the second terminal device sends the radio resource connection management signaling to the first terminal device by adding forwarding instruction information to the radio resource connection management signaling.
- the forwarding instruction information is used to instruct the first terminal device to forward signaling of the second terminal device to the network side device.
- D2D communication is used as an example.
- the second terminal device and the first terminal device communicate with each other by using an LTE-D2D technology in the 3GPP standard, because a data packet is sent in a broadcast mode in LTE-D2D, after receiving a data packet sent by the second terminal device through broadcasting, the first terminal device cannot determine whether the data packet needs to be forwarded to RRC signaling of the base station. Therefore, the second terminal device adds forwarding instruction information to a MAC PDU of a D2D message sent through broadcasting, to instruct the first terminal device receiving the D2D message to forward connection management information carried in the MAC PDU of the D2D message to the base station.
- FIG. 9 is a schematic structural diagram of a part of a MAC PDU of a D2D message.
- two R bits in oct1 may be used to indicate whether a data packet needs to be forwarded. It is assumed that in the two R bits, "00" indicates receiving and self-processing, "01" indicates receiving and forwarding to another D2D UE, and "10" indicates receiving and forwarding to a base station. If there are more processing types, more bits may be occupied to carry forwarding instruction information. For example, three or four R bits are occupied. A third R bit in the oct1 may be used to identify whether a data packet carried in a MAC PDU is signaling or common service data.
- a logical channel identifier (Logical channel identification, LCID) carried in the MAC PDU is an identifier of a logical channel group corresponding to a radio bearer that is on a UU interface of the first terminal device and that is used to forward a message of the second terminal device.
- LCID Logical channel identification
- Step 802 The first terminal device forwards the radio resource connection management signaling to a network side device after determining that a destination of the radio resource connection management signaling is the network side device.

- the network side device is a base station.
- the base station configures a dedicated signaling radio bearer (Signal Radio Bearer, SRB) between the first terminal device and the base station for the first terminal device, for example, an SRB 5 that is specially used by the first terminal device to transmit RRC signaling of the second terminal device.

- the network side device configures only one dedicated radio bearer for the first terminal device, and the dedicated radio bearer is used by the first terminal device to forward signaling of the second terminal device to the network side device.
- the network side device cannot identify a source of signaling based only on a radio bearer carrying the signaling, and needs to add source indication information to the signaling.
- the network side device determines that the signaling is generated by the second terminal device; or if the network device identifies that the source indication information in the signaling indicates the first terminal device, the network device determines that the signaling is generated by the first terminal device.
